Description

  The present invention relates to a vehicle air cleaner and a mold unit for manufacturing an air cleaner. More specifically, the air cleaner case is improved in airtightness and rigidity to reduce radiation noise generated during traveling. The present invention relates to a vehicle air cleaner capable of improving NVH performance and a mold unit for manufacturing an air cleaner.

Usually, a vehicle intake system sucks external air and uses it for combustion. Therefore, if foreign matter flows into the engine, problems such as abnormal combustion or troubles caused by the engine may occur. Accordingly, the external air to be sucked passes through the air cleaner, and the impurities contained in the air are filtered by the filtering member.
The filter member is a consumable part and is provided inside the air cleaner, and must be replaced at regular intervals. In “Vehicle Air Cleaner” of Korean Patent Publication No. 2013-0061599A, the air cleaner is constructed as a drawer type so that the filter member can be easily used by using the front cover instead of removing the cover from the body. It can be stored and pulled out.

  In the vehicle air cleaner, the cover and body of the air cleaner are joined by vibration welding using ultrasonic waves. In general, ultrasonic fusion uses ultrasonic vibrations to fuse a workpiece. Electric power is input to the fuser and electric energy is generated by a power supply (Power Supply). Is converted into mechanical vibration energy by a vibrator and a booster, and then the vibration energy is transmitted to a workpiece through a tool horn. Then, if vibration energy is transmitted to the object to be processed through the tool horn, frictional heat due to powerful vibration is instantaneously generated, and melting and adhesion are performed on the joint surface with the object to be processed. Such an ultrasonic fusion method is widely used for fusion of plastics and metals, sealing of fabrics and films, fusion of cable terminals, and the like.

However, conventionally, since the fusion surface where the cover and the body are fused is located on the upper side and the filtration member is located at the storage port where the filter member is accommodated or pulled out, the dimensions due to deformation after the fusion process of the cover and the body There was a problem that it was difficult to ensure safety. In order to solve the above-described problems, when the fusion surface is formed lower than the conventional one, there is a problem that a sufficient space is not secured and a seal structure is not formed.
Also, when the cover and body are fused, the reinforcing ribs that can increase the rigidity in terms of molding conditions can be formed only in one vertical direction due to the flange structure formed to fix the cover and body. There is a drawback of not.

FIG. 6 is a view showing a driving member 900 and a filtering member 800 of a vehicle air cleaner according to another embodiment of the present invention.

  A vehicle air cleaner according to a preferred embodiment of the present invention has a housing space formed therein, an air intake port 110 through which air can be sucked in on one side, and a side bent on the upper side. A support portion 130 is formed, and a plate-like reinforcing member 150 having a predetermined thickness is formed on the upper side of the accommodation space. The body 100 is coupled to the upper side of the body 100, and an accommodation space is formed inside. A cover 300 having a discharge port 310 through which air can be discharged and an engaging portion 330 bent to the side is formed on the lower side, and the body 100 and the opening provided on the front surface of the cover 300. A storage opening 500 serving as an entrance through which the filtering member 800 is stored or pulled out, and a plate-shaped storage opening 500 that is coupled to the front surface of the storage opening 500 and opens and closes the storage opening 500. No.

  The air flow of the air cleaner according to the present invention will be described. The air sucked from the outside of the vehicle is sucked into the air cleaner through the air inlet 110 of the body 100, and impurities are filtered by the filter member 800. It is supplied to the engine (not shown) through the discharge port 310. In the vehicle air cleaner, the body 100 and the cover 300 form a sealed space, and the filter member 800 is coupled in the sealed space, that is, above the support portion 130 of the body 100. When the filter member 800 is replaced, the front lid 700 is opened and closed, and the filter member 800 is stored or pulled out through the storage port 500.

  The filtering member 800 is stored or attached to the air cleaner through the storage port 500. The storage port 500 is formed on one side of the body 100 and the cover 300 where the support portion 130 and the engagement portion 330 are in contact with each other. Therefore, the storage port 500 is formed in a shape corresponding to the filtering member 800. In the present embodiment, the filter member 800 has been described as an example of a dry type using filter paper or synthetic fiber. However, in some cases, the filter member 800 can also be used as a wet type. It can be changed as much as you like depending on the environment.

The filter member 800 includes a filter paper 810 that filters impurities, and a frame member 830 that is formed on the upper side of the filter paper and that surrounds the outer periphery of the filter paper 810. The filter paper 810 is laminated in multiple stages and formed to have a sufficient filtration area, and the frame member 830 is formed of a frame having a shape corresponding to the inner storage space of the air cleaner, and the body has a flange that protrudes laterally and extends upward. It is firmly supported by 100.
On the side surface of the body 100, lattice-like ribs 160 and 170 are projected outward at predetermined intervals. Conventionally, due to the molding characteristics of the body, only the longitudinal ribs are formed in the removal direction of the mold unit, so the rigidity in the width direction is low. In addition, due to the characteristics of the conventional mold unit, it is difficult to apply a separate reinforcing structure for increasing the rigidity in the width direction. In particular, when the seating surface is wide, the rigidity of the central portion is low, so that there is a high risk of damage due to vehicle vibration or impact.

  However, in the present invention, the mold units 200, 400, and 600 are separately formed and injection-molded so as to form not only the longitudinal ribs 160 but also the lateral ribs 170, so that compared to the conventional body. The rigidity can be increased. Such an effect is difficult to obtain with a conventional mold unit. Therefore, by molding using separate mold units 200, 400, and 600, the displacement of the air cleaner is restrained and another lateral rib 170 is formed. In addition, a reinforcing structure such as the reinforcing member 150 is applied. The detailed contents of the vehicle air cleaner mold units 200, 400, and 600 will be described later.

  The support part 130 of the body 100 is extended sideways by a predetermined length, then extended downward, and further extended sideways. Further, the engaging portion 330 of the cover 300 is extended to the side by a predetermined length, then extended downward, and further extended to the side. Accordingly, the support portion 130 of the body 100 and the engagement portion 330 of the cover 300 are in close contact with each other and are more firmly engaged. In addition, after the body 100 and the cover 300 are joined, vibrations to the left and right are applied by ultrasonic waves and fused together, so that the air cleaner is tightly adhered to each other and the air cleaner has a high airtight effect. In some cases, the engagement protrusion 331 and the engagement hole 131 may be further formed in the support part 130 and the engagement part 330 to realize the double fixing and sealing effect. In addition, extension portions 133 and 333 that are extended in the vertical direction can be formed at the ends of the support portion 130 and the engagement portion 330, respectively.

  A mounting groove 190 is formed in the body 100 below the support portion 130. The support part 130 is extended by a predetermined length from the upper side to the side of the body 100, bent downward, and further extended to the side. A fusion jig (not shown) is coupled to the mounting groove 190 when the body 100 and the cover 300 are vibration-fused by ultrasonic waves or the like. Therefore, there is an advantage that a separate jig is not used when the body 100 and the cover 300 are fused, and there is an effect that the body 100 and the cover 300 are more firmly supported by the support portion 130 and the mounting groove 190.

  The body 100 is integrally formed with the body 100, and a reinforcing member 150 having an inverted “U” cross section is formed. The reinforcing member 150 has an effect of increasing the fastening rigidity between the body 100 and the cover 300. The reinforcing member 150 is formed with a plurality of reinforcing holes 151 having a predetermined depth in the vertical direction. Accordingly, the reinforcing hole 151 is configured such that when the mold units 200, 400, 600 are removed after the body 100 is molded, the removal direction of the mold units 200, 400, 600 is different from the conventional removal direction. Therefore, the working process can be performed more easily when the body 100 is molded, and the reinforcing hole 151 can be formed in the support portion 130 of the body 100 or the like.

Further, the frame member 830 of the filtering member 800 is coupled to the space between the support portion 130 of the body 100 and the engaging portion 330 of the cover 300. At this time, by providing the clamp member 180 between the upper side of the frame member 830 and the support portion 130, the filter member 800 can be supported more stably, and the body 100 and the cover 300 can be stably sealed. It becomes.
FIG. 6 is a view showing a drive member 900 and a filter member 800 of a vehicle air cleaner according to still another embodiment of the present invention. The figure shows a drive member 900 incorporated in the air cleaner and a filter member 800 coupled to the upper side of the drive member 900. This will be described with a driving member 900 further provided between the support portion 130 of the air cleaner body 100 of FIG. 1 and the upper side of the filtering member 800.

The driving member 900 of the body 100 includes a plurality of camshafts 930 on which a plurality of cams 910 are mounted and a bevel gear 950 that connects the camshafts 930 to each other. Therefore, the filter member 800 can be stored or pulled out by driving the drive member 900.
More specifically, when the user rotates a handle 970 provided on the drive member 900, the driving member 900 rotates the camshaft 930 by the rotation of the handle 970, and the cam 910 rotates by the rotation of the camshaft 930. By rotating, the filtering member 800 is housed or pulled out while moving up and down in the vertical direction. The camshaft 930 is provided on each of the remaining three surfaces excluding the surface of the body 100 and the cover 300 on the storage port 500 side, and a bevel gear 950 is provided at an end portion where the camshaft 930 and the camshaft 930 meet with each other. All the camshafts 930 mesh with each other and rotate.

A plurality of cams 910 are installed on the camshaft 930 along the longitudinal direction. The cam 910 is formed so as to have a diameter larger than the axial diameter of the camshaft 930 and is formed so that one side is expanded, and the user holds the handle 970 provided at one end of the camshaft 930. When rotating, the protruding portion of the cam 910 faces downward and is supported by the support portion 130 formed on the body 100 to raise the filter member 800.
As shown in FIG. 6, the cam 910 is formed so that the upper surface and the side surface on the drawing form a right angle in the portion protruding to one side, and the lower surface is formed in a round shape, thereby Formed to rotate only.

That is, the portion protruding at a right angle of the cam 910 can not be rotated by the contact of the support portion 130, and can be rotated only at the round portion.
Further, a rotation limiting protrusion 911 is provided on the other side of the cam 910. The rotation restricting protrusion 911 is configured to rotate only when a predetermined pressure is applied when the user rotates the camshaft 930 to raise the filter member 800, and the vehicle travel vibration and impact For example, the camshaft 930 is naturally restricted from rotating.

  Therefore, as shown in FIG. 6, when the driving member 900 is inserted into the storage port 500 formed in the body 100 and the cover 300 in the state of being coupled to the lower portion of the flange of the filtering member 800, After inserting the filtering member 800 in a state where the extended protruding portion of 910 is rotated in a horizontal direction and the filtering member 800 is completely inserted, the extended protruding portion of the cam 910 is directed downward by rotating the handle 970. The camshaft 930 is rotated as described above. Accordingly, the protruding portion of the cam 910 is supported by the support portion 130 formed on the body 100, and the filtering member 800 is in close contact with the upper side of the storage port 500 while rising upward.

At this time, when the camshaft 930 provided with the handle 970 is rotated, the camshaft 930 rotates, and the pair of camshafts 930 can be rotated at the same time. Even if only the camshaft 930 is rotated, all the camshafts 930 can be rotated.
Therefore, since the filter member 800 comes into close contact with the body 100 and the cover 300 of the air cleaner by driving the drive member 900, the filter member 800 is not swollen by the fluid pressure flowing in the air cleaner and no vibration noise is generated.

In addition, since the filter member 800 is in close contact with the body 100 and the cover 300, air leakage can be prevented, thereby preventing the generation of leakage sound. Further, since the filter member 800 is easily and simply brought into close contact with the body 100 and the cover 300 by a simple operation of rotating the drive member 900, there is an effect of eliminating the generation of noise due to the occurrence of a gap.
According to the vehicle air cleaner, the rigidity of the air cleaner is increased by adding the lateral rib 170 to the side surface of the body 100 and overlapping the reinforcing member 150 on the inside of the body 100. Therefore, the pulsation generated by vibration or impact generated while the vehicle is running is vibrated in the air cleaner to prevent the generation of noise or vibration, thereby improving the NVH performance of the vehicle.

  Further, the fusion part where the body 100 and the cover 300 are fused can be formed on the lower side compared to the conventional case, and a sufficient storage space in the air cleaner can be secured. There is an advantage that it can be fused all around. In particular, by configuring the filter member 800 so that it can be housed or pulled out by the camshaft 930, even when the drive member 900 is mounted, a sufficient space is secured and stable sealing is possible. In addition, by forming as described above, it is possible to ensure basic rigidity at the time of vibration fusion, and it is possible to improve fusion quality and increase dimensional consistency by restraining fusion displacement by the attachment groove 190. There is an advantage to. Accordingly, there is an effect that the stable sealing performance of the vehicle air cleaner is ensured and the weight and cost are reduced by increasing the airtightness and the fastening rigidity.

The slide mold 600 has a predetermined thickness and a predetermined width, and is formed long in the vertical direction. On the inward surface, lattice-like lattice grooves 610 are formed in the horizontal direction and the vertical direction. Unlike the conventional case, the lattice grooves 610 can further increase the rigidity of the body 100 by forming not only the longitudinal rib 160 but also the lateral rib 170 on the side surface of the body 100. Here, the slide mold 600 is formed so as to correspond to the second engagement recess 410 and the first engagement recess 210 formed in the upper mold 400 and the lower mold 200, and is slid and engaged in the vertical direction.
